To all whom it 711er/ concern.'

Be it known that l, MICHAEL PARIS FonAN, a subject ol the King of GreatBritain, and a resident of Johannesburg, Transvaal, South Africa, haveinvented a new Developing-T ray, of which the following is a full,clear, and exact description.

This invention relates to trays adapted to support photographic platesor films, and has 'for its object to provide a safe means for holdingplates or films while being developed, and adapted to enable the platecr films to be examined by transmitted light without being removed fromthe tray, and also to enable the entire operation to be accomplishedwithout requiring the 'lilm or negative to be handled by the operator.

Such objects l accomplish by the means illustrated in the accompanyingdrawings, in which drawings like characters of reference indicate likeparts throughout the views, and in which Figure 1 is a perspective viewof a device embodying my invention; Fig. 2 is a plan of a deviceembodying my invention with a photographic plate supported thereon', andFig. 3 is a vertical transverse section of the tray or plate shown inFig. 2 taken on the line 313 of Fig. 2.

As illustrated in the drawings, my device consists of a tray havingVl'lat longitudinal side plates l and end plates 2 Yforming arectangular ledge with an open interior, the ledge being thereby adaptedto support a photographic plate 3, as shown in Fig. 3, and the opencentral portion of the tray permitting the plate to be examined bytransmitted light without being handled directly by the user, the platebeing held safely on the tray by means of lips 4 which are formed ononer i l l l i l l l l l l l of the end plates 2 and extend verticallytherefrom, and retaining lips 5 extending transversely of the sideplates or ledges of the tray and separated 'from the surface thereof andImproved so as to hold a photographic plate between the retaining lipsand the ledge ot the tray, as shown in Figs. 2 and 3. The tray isprovided with side bars 6 by means of which the tilm or negative may bereadily immersed in a developing bath, and the side bars 6 are connectedwith the side plates l of the tray by means of vertical bars or plates7. The centrai plates or bars 7 Jiurnish a support for the transverseretaining lips 5, and said lips may, if desired, be made integral withsaid central bars, and in Inost instancesl prefer to make the retaininglips 4 integral with the end plates 2 of the tray, as shown in Fig. l.

The tray Inay be made of any suitable size to suit the various negativesand cut iilms, and may be constructed of any suitable Inaterial, such asxylonite, ebcnite, granitine, enameled iron or other suitable material.

Having thus described my invention, l claim as new and desire to secureby Letters Patent:

A developing tray consisting of a bent sheet having an open baseportion, vertical side walls partially cut away, and stops pro videdupon the side walls and base, respectively, the stops upon the sidewalls being spaced 'from the base portion, substantially as and for thepurpose set Jforth.

ln testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
